易门烟区烤烟适宜移栽方式研究

Research on the Suitable Transplanting Methods for Flue-Cured Tobacco in Yimen Tobacco Growing Area

摘要: 目的：探究易门烟区适宜的移栽方式以促进烤烟产质量的提升。方法：本研究设置常规不盖膜移栽、膜下小苗移栽、明水抛苗移栽、移栽器膜下移栽四种移栽方式，分析不同移栽方式对于烤烟田间农艺性状、初烤烟叶外观质量、化学成分和经济性状的影响。结果：移栽器移栽处理的烟叶外观质量得分高，上部叶化学成分相比其他处理更协调，经济性状最高，显著高于不盖膜移栽处理，明水抛苗移栽处理的烟叶外观质量最优，中下部叶化学成分协调，经济性状仅次于移栽器移栽处理。结论：明水抛苗移栽和移栽器膜下移栽两种移栽方式是适合易门烟区烤烟生产的移栽方式。

Abstract: Object: To explore the suitable transplanting methods in Yimen tobacco-growing area to enhance the yield and quality of flue-cured tobacco. Methods: Four transplanting methods, namely conventional transplanting without mulching, small-plant transplanting under mulch, water-throwing transplanting, and transplanting with a planter under mulch, were set up in this study. The effects of different transplanting methods on the agronomic traits in the field, the appearance quality of raw tobacco leaves, chemical composition, and economic traits were analyzed. Results: The appearance quality score of the tobacco leaves in the planter transplanting treatment was the highest. The chemical composition of the upper leaves was more balanced compared to other treatments, and the economic traits were the best, significantly higher than those in the no-mulch transplanting treatment. The water-throwing transplanting treatment had the best appearance quality of the tobacco leaves, with balanced chemical composition of the middle and lower leaves, and the economic traits were second only to the planter transplanting treatment. Conclusion: Water-throwing transplanting and planter transplanting under mulch are suitable transplanting methods for flue-cured tobacco production in Yimen tobacco-growing area.
